Start-up costs and pecuniary externalities as barriers to economic development

We use a dynamic monopolistic competition model to show that an economythat inherits a small range of specialized inputs can be trapped into alower stage of development. The limited availability of specialized inputsforces the final goods producers to use a labor intensive technology, whichin turn implies a small inducement to introduce new intermediate inputs. Thestart--up costs, which make the intermediate inputs producers subject todynamic increasing returns, and pecuniary externalities that result from thefactor substitution in the final goods sector, play essential roles in themodel.

Introducing systematic dispatcher-assisted cardiopulmonary resuscitation (telephone-CPR) in a non-Advanced Medical Priority Dispatch System (AMPDS): implementation process and costs.

OBJECTIVE: In order to improve the quality of our Emergency Medical Services (EMS), to raise bystander cardiopulmonary resuscitation rates and thereby meet what is becoming a universal standard in terms of quality of emergency services, we decided to implement systematic dispatcher-assisted or telephone-CPR (T-CPR) in our medical dispatch center, a non-Advanced Medical Priority Dispatch System. The aim of this article is to describe the implementation process, costs and results following the introduction of this new "quality" procedure. METHODS: This was a prospective study. Over an 8-week period, our EMS dispatchers were given new procedures to provide T-CPR. We then collected data on all non-traumatic cardiac arrests within our state (Vaud, Switzerland) for the following 12months. For each event, the dispatchers had to record in writing the reason they either ruled out cardiac arrest (CA) or did not propose T-CPR in the event they did suspect CA. All emergency call recordings were reviewed by the medical director of the EMS. The analysis of the recordings and the dispatchers' written explanations were then compared. RESULTS: During the 12-month study period, a total of 497 patients (both adults and children) were identified as having a non-traumatic cardiac arrest. Out of this total, 203 cases were excluded and 294 cases were eligible for T-CPR. Out of these eligible cases, dispatchers proposed T-CPR on 202 occasions (or 69% of eligible cases). They also erroneously proposed T-CPR on 17 occasions when a CA was wrongly identified (false positive). This represents 7.8% of all T-CPR. No costs were incurred to implement our study protocol and procedures. CONCLUSIONS: This study demonstrates it is possible, using a brief campaign of sensitization but without any specific training, to implement systematic dispatcher-assisted cardiopulmonary resuscitation in a non-Advanced Medical Priority Dispatch System such as our EMS that had no prior experience with systematic T-CPR. The results in terms of T-CPR delivery rate and false positive are similar to those found in previous studies. We found our results satisfying the given short time frame of this study. Our results demonstrate that it is possible to improve the quality of emergency services at moderate or even no additional costs and this should be of interest to all EMS that do not presently benefit from using T-CPR procedures. EMS that currently do not offer T-CPR should consider implementing this technique as soon as possible, and we expect our experience may provide answers to those planning to incorporate T-CPR in their daily practice.

Health care provider choice in the case of patient-initiated contacts. An extended version of discrete choice of model demand

This paper analyzes the nature of health care provider choice inthe case of patient-initiated contacts, with special reference toa National Health Service setting, where monetary prices are zeroand general practitioners act as gatekeepers to publicly financedspecialized care. We focus our attention on the factors that mayexplain the continuously increasing use of hospital emergencyvisits as opposed to other provider alternatives. An extendedversion of a discrete choice model of demand for patient-initiatedcontacts is presented, allowing for individual and town residencesize differences in perceived quality (preferences) betweenalternative providers and including travel and waiting time asnon-monetary costs. Results of a nested multinomial logit model ofprovider choice are presented. Individual choice betweenalternatives considers, in a repeated nested structure, self-care,primary care, hospital and clinic emergency services. Welfareimplications and income effects are analyzed by computingcompensating variations, and by simulating the effects of userfees by levels of income. Results indicate that compensatingvariation per visit is higher than the direct marginal cost ofemergency visits, and consequently, emergency visits do not appearas an inefficient alternative even for non-urgent conditions.

Relative price riddles in international business cycle theory: Are transport costs the explanation?

We study relative price behavior in an international business cyclemodel with specialization in production, in which a goods marketfriction is introduced through transport costs. The transporttechnology allows for flexible transport costs. We analyze whetherthis extension can account for the striking differences betweentheory and data as far as the moments of terms of trade and realexchange rates are concerned. We find that transport costs increaseboth the volatility of the terms of trade and the volatility of thereal exchange rate. However, unless the transport technology isspecified by a Leontief technology, transport costs do not resolvethe quantitative discrepancies between theory and data. Asurprising result is that transport costs may actually lower thepersistence of the real exchange rate, a finding that is in contrastto much of the emphasis of the empirical literature.

Implementação do sistema de custeio baseado em actividades (CBA) numa Instituição de Ensino Superior em Cabo Verde

Actualmente, a gestão de gastos assume um papel fundamental nas empresas modernas. A globalização, aliada às novas tecnologias, exige que essas empresas sejam ágeis e competentes. Neste contexto, a gestão eficiente dos recursos e a obtenção de informações precisas que apoiem na tomada de decisão, dependerão em grande parte, de um sistema de custo. A utilização de diversas tecnologias e ferramentas faz com que as empresas tenham cada vez mais gastos indiretos relativamente aos gastos diretos. Logo, o método CBA surgiu como alternativa aos sistemas de custeio tradicionais numa tentativa de solucionar ou, pelo menos, minimizar o problema de atribuição dos gastos indiretos. O presente trabalho pretende abordar o método CBA e propor uma metodologia de implementação do sistema numa Instituição de Ensino Superior, evidenciando e discutindo as principais vantagens e desvantagens associadas a esta metodologia e identificando as suas contribuições para a gestão das IES. De acordo com as pesquisas feitas, conclui-se que nenhuma das IES em São Vicente possui um sistema de contabilidade de gestão, mas verificou-se que todas têm conhecimento deste sistema e consideram-no o melhor método de gestão para análise dos gastos. Os resultados obtidos no estudo de caso demonstram que o objetivo foi atingido, apurandose que o método CBA é o mais adequado para o suporte à gestão, tendo em conta que ultrapassa as insuficiências de informação sobre os gastos. Currently, cost management plays a key role in modern business. The globalization, allied to the new technologies, demands that those companies are agile and qualified. In this context, an efficient management of the resources and the gathering of precise information which support the decision-making process will depend, largely, of an effective cost management system. The use of different technologies and tools makes companies have more indirect costs than direct. Therefore, the ABC method was devised as an alternative to the conventional means of costing in an attempt of solving or, at least, minimizing the problem of the attribution of indirect costs. Our work intends to analyze the ABC method and to propose a methodology of implementation of such system in an Institution of Higher Education, showing and discussing the main advantages and disadvantages associated with this methodology and identifying its contributions for the administration of these Institutions. Our research has shown that, none of the IHEs in São Vicente has a management accounting system, although all have knowledge of it and consider it as being the best administration method for the analysis of expenses. The results obtained in the case study demonstrate that the objective was reached: to conclude the ABC method is the most adequate to support the administration, as it overcomes the problem of lack of information on the running costs.

Direct MR arthrography of the shoulder under axial traction: Feasibility study to evaluate the superior labrum-biceps tendon complex and articular cartilage.

PURPOSE: To assess the value of adding axial traction to direct MR arthrography of the shoulder, in terms of subacromial and glenohumeral joint space widths, and coverage of the superior labrum-biceps tendon complex and articular cartilage by contrast material. MATERIALS AND METHODS: Twenty-one patients investigated by direct MR arthrography of the shoulder were prospectively included. Studies were performed with a 3 Tesla (T) unit and included a three-dimensional isotropic fat-suppressed T1-weighted gradient-recalled echo sequence, without and with axial traction (4 kg). Two radiologists independently measured the width of the subacromial, superior, and inferior glenohumeral joint spaces. They subsequently rated the amount of contrast material around the superior labrum-biceps tendon complex and between glenohumeral cartilage surfaces, using a three-point scale: 0 = no, 1 = partial, 2 = full. RESULTS: Under traction, the subacromial (Δ = 2.0 mm, P = 0.0003), superior (Δ = 0.7 mm, P = 0.0001) and inferior (Δ = 1.4 mm, P = 0.0006) glenohumeral joint space widths were all significantly increased, and both readers noted significantly more contrast material around the superior labrum-biceps tendon complex (P = 0.014), and between the superior (P = 0.001) and inferior (P = 0.025) glenohumeral cartilage surfaces. CONCLUSION: Direct MR arthrography of the shoulder under axial traction increases subacromial and glenohumeral joint space widths, and prompts better coverage of the superior labrum-biceps tendon complex and articular cartilage by contrast material.

Gender gaps in policy making: Evidence from direct democracy in Switzerland

In spite of increasing representation of women in politics, little is known about their impact onpolicies. Comparing outcomes of parliaments with different shares of female members does not identifytheir causal impact because of possible differences in the underlying electorate. This paper usesa unique data set on voting decisions to sheds new light on gender gaps in policy making. Ouranalysis focuses on Switzerland, where all citizens can directly decide on a broad range of policiesin referendums and initiatives. We show that there are large gender gaps in the areas of health,environmental protection, defense spending and welfare policy which typically persist even conditionalon socio-economic characteristics. We also find that female policy makers have a substantial effect onthe composition of public spending, but a small effect on the overall size of government.

Does foreign direct investment crowd out domestic entrepreneurship?

In analyzing firm entry and exit across Belgian manufacturing industries,this paper presents evidence that import competition and foreign directinvestment discourage entry and stimulate exit of domestic entrepreneurs.These results are in line with theoretical occupational choice modelsthat predict foreign direct investment would crowd out domesticentrepreneurs through their selections in product and labor markets.However, the empirical results also suggest that this crowding out effectmay be moderated or even reversed in the long-run due to the long termpositive effects of FDI on domestic entrpreneurship as a result oflearning, demonstration, networking and linkage effects between foreignand domestic firms.
